Definitions
- the present invention relates to a ball joint mechanism which is adapted to permit setting of two members relative to each other, said members forming part of a settable device for gas transport, whereby one of said members preferably consists of a gas conduit and the other member preferably of a nozzle which is connected with said gas conduit and settable in various positions in relation thereto, and whereby the device for gas transport preferably is a settable device for the exhaustion or extraction of unhealthy gases from workplaces.
- Ball joint mechanisms for the above purpose are known from the U.S. Pat. No. 4,540,202. In this publication there is schematically shown a ball coupling, but this is not settable and adjustable in its friction distance.
- Ball joint mechanisms comprising two balls which cooperate with a spring element are known from the U.S. Pat. No. 1,827,432 and the FR-PS 699 369, but in these prior art ball joint mechanisms it is not possible to set or readjust the spring force by simple measures.
- the object of the present invention has therefore been to permit, at a ball joint mechanism of the above type, setting or readjustment by hand of the spring forces.
- the ball joint mechanism By providing the ball joint mechanism with said characterizing features, its spring force can be set or readjusted by hand very quickly and precisely by changing the mutual position of the two members of the joint housing. By being able to carry out the change of the spring force in this way, no operations need to be done in the ball joint mechanism nor are any special tools required.
- FIG. 1 with a side view illustrating an adjustable device for gas transport having a ball joint mechanism according to the invention
- FIG. 2 is a perspective view, partly in section, of the ball joint mechanism according to the invention
- FIG. 3 is an exploded perspective view of the ball joint mechanism according to the invention
- FIG. 4 is a longitudinal section of the ball joint mechanism according to the invention.
- the device 1 illustrated in FIG. 1 is a settable or adjustable device for gas transport, e.g. for the exhaustion or extraction of unhealthy welding gases from welding work places.
- a device 1 is usually designated as a spot extraction device and it consists of substantially a stand 2 and a fan 3 mounted thereon, said fan 3 being connected with a passage system 4 for the discharge of extracted gases.
- An elbow pipe 5 is provided on the stand 2, which pipe can pivot about a vertical axis.
- a settable arm system 6 extends from the elbow pipe 5, said arm system having two links 7 and 8 permitting pivoting of the arms in said system about horizontal axes.
- the arm system 6 carries a gas conduit 9 and a nozzle 10 which is connected with said gas conduit. This nozzle 10 is connected with the arm system 6 and/or parts of the gas conduit through a link which is adapted to give extensive movability and many setting possibilities of the nozzle 10 relative to the gas conduit 9.
- this link is designed as ball joint mechanism 11 comprising a joint housing 12 with two rotatably or pivotally mounted balls 13, 14.
- One of the balls 13 is through a coupling means 15 connectable with the arm system 6 and/or gas conduit 9 and the nozzle 10 is connected with the other ball 14 through a coupling means 16.
- Each ball 13, 14 is mounted such that it can rotate about its centre C.
- the balls 13, 14 cooperate with first friction elements 17, 18 and other friction elements 19, 20 for obtaining the required frictional resistance.
- spring elements 21 are provided for compensating eventual wear of said friction elements 17, 18 and/or 19, 20 and/or the ball surfaces cooperating therewith.
- the ball housing 12 preferably comprises two cylindrical housing members 22, 23 of which one member 22 is a female member with a widened portion 24 having internal threads 25.
- the other member 23 is a male member with an end portion 26 having external threads 27 and dimensioned such that it can be screwed more or less into the female member 22.
- Said one member 22 has a bearing space 28 for one ball 13 and said other member 23 a bearing space 29 for the other ball 14.
- the bearing space 28 is defined preferably at one end portion by an inwardly directed annular flange 30, defining a circular opening 31 having less diameter than the ball 13.
- the bearing space 29 is defined preferably at one end portion by an inwardly directed, annular flange 32, defining a circular opening 33 having less diameter than the ball 14.
- the openings 31, 33 are sized or dimensioned such that a smaller portion of the balls 13, 14 protrude therethrough. Furthermore, the openings 31, 33 are dimensioned such that the balls 13, 14 can pivot from a neutral position N a limited number of degrees in all directions until the coupling means 15, 16 prevent further pivoting by engaging the joint housing 12 and preferably the flanges 30, 32 at the openings 31, 33.
- the joint housing 12 preferably has obliquely outwardly directed edge portions 34, 35 such that the balls 13, 14 can pivot somewhat more outwards from their neutral position before the coupling means 15, 16 engage the joint housing 12 than if these oblique edge portions 34, 35 were lacking. Said edge portions 34, 35 can preferably extend in parallel with or substantially in parallel with extensions outwards to radii of the balls 13, 14.
- Each ball 13, 14 is preferably pivotable outwards from its neutral position N about 40°-50° in all directions, preferably about 45°, before these coupling means 15, 16 engage the housing 12.
- each ball is preferably rotatable about a centre line CL when it is located in its neutral position N as well as in all other setting positions, e.g. Y1 and Y2.
- the ball joint mechanism 11 is capable of pivoting within a spherical sector of about ⁇ 45° per ball 13 or 14, i.e. about ⁇ 90° for both balls 13, 14.
- the ball joint mechanism 11 is capable of an unlimited rotating movement irrespective of whether it is set in neutral position N or in any other position Y1 or Y2.
- the friction elements 17, 18 are provided within the balls 13, 14 in the joint housing 12, and the friction element 19 is provided in the bearing space 28 of the joint housing 12 outside the ball 13, such that outer portions of said ball 13 engage this friction element 19. Also, the friction element 20 is mounted in the bearing space 29 of the joint housing 12 outside the ball 14, such that outer portions of said ball 14 engage said friction element 20.
- the friction elements 19, 20 are annular in shape and they engage preferably the inside of the respective annular flange 30, 32.
- One friction element 18 consists preferably of a washer, one side of which defines a friction surface 36 through which said washer is adapted to engage one ball 14. From the other side 37 of the washer there is protruding an annular outer flange 38 and a centre pin 39.
- the centre pin 39 is adapted to define a bearing pin for the spring element 21 and the outer flange 38 is adapted to surround said spring element.
- the other friction element 17 consists preferably of another washer, one side of which defines a friction surface 40 through which said friction element 17 engages the other ball 13.
- the other side of the friction element 17 engages the spring element 21 and preferably includes a recess 42 for the centre pin 39.
- the spring element 21 preferably comprises a cup spring package including two pairs of cup springs 43-46.
- the cup springs in each pair are preferably located such that their outer portions engage each other.
- On both sides of the cup spring package there are preferably located washers 47, 48 and the cup springs 43-46 as well as said washers 47, 48 are threaded onto the centre pin 39 and held in position thereby.
- the joint housing 12 is capable of holding the balls 13, 14, friction elements 17-20 and spring element 21 in position, to protect the friction surfaces and inner parts of the joint from dirt and to apply the force giving the correct friction between the balls 13, 14 and the friction surfaces. Furthermore, the joint housing 12 has due to its partition an advantageous strength and the flow of power in tangential direction is not broken. Additionally, said construction of the joint housing 12 is aerodynamically advantageous and its construction also limits the movability of the balls 13, 14 so that no locking occurs.
- the friction elements 19, 20 permit fixing of the balls 13, 14 in the joint housing 12 and they also present dirt from penetrating into said housing 12, especially if the ball joint mechanism 11 is surrounded by a tight protective cover, e.g. a rubber bellows.
- the spring element 21 is provided to spring outwards e.g. for compensating eventual wear of said friction elements 17-20 and thereby preferably maintain the desired frictional force of the ball joint mechanism 11.
- cup springs 43-46 as spring element 21, said element gets a degressive spring constant, whereby washers 47, 48 located on opposite sides of the cup spring package prevent wear of adjacent friction elements 17, 18.
- the present ball joint mechanism has a resilience of flattened or level characteristic and the friction elements allow a small "slip-stick”-effect, giving a uniform and constant frictional moment also after some wear of said friction elements. Furthermore, the embodiment of the ball joint mechanism 11 described above has the advantage of being totally independent of the direction of the load moment.
- One coupling means 15 of the completed and mounted ball joint mechanism 11 is connected with the arm system 6 and/or the gas conduit 9 and the other coupling means 16 to the nozzle 10. If there is a need for changing the spring forces of the ball joint mechanism 11, this change is carried out by altering the mutual position of the members 22, 23 of the joint housing 12 until the desired spring forces are obtained. Thereafter, a flexible hose 49 is threaded onto and over the ball joint mechanism 11 and said hose is connected with the nozzle 10 and with a pipe portion 50 such that it defines a part of the gas conduit 9. If readjustment of the spring forces of the ball joint mechanism 11 is required, the hose 49 is released from the nozzle 10 or the pipe portion 50, whereafter the hose 49 is moved aside for exposure of the ball joint mechanism 11. After the readjustment, the hose 49 is reconnected such that the gas conduit 9 is reestablished.
- the joint housing 12 can have another shape and consist of another number of members which are connected with each other in other ways; the joint housing 12 can include two members which can be connected with each other by means of a bayonet mount instead of threads; the spring element 21 can be of another type, consist of another number of members and be located in other ways; the friction elements can be of another type, consist of another number of members and be located in other ways; the ball joint mechanism 11 can be mounted between other members of a gas transport device or said device can comprise a plurality of ball joint mechanisms 11; finally, the gas transport device can be of another type than for extracting welding fume or similar.
